HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-ethylpentanoic acid is a chiral amino acid derivative featuring a fluorenylmethoxycarbonyl (Fmoc) protecting group. This moiety ensures stable incorporation during solid-phase peptide synthesis, enabling efficient chain elongation. The ethyl-substituted aliphatic side chain provides steric differentiation, enhancing selectivity in coupling reactions and facilitating purification. Bench-stable under standard conditions, this reagent streamlines the preparation of complex peptides with defined stereochemistry.

Application

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-ethylpentanoic acid serves as a robust chiral building block for peptide synthesis, leveraging the fluorenylmethoxycarbonyl (Fmoc) group for orthogonal protection. Its sterically defined side chain enables efficient coupling with diverse amine nucleophiles, while the Fmoc moiety ensures high stability under basic conditions and facile removal during standard deprotection protocols. This compound facilitates sequence-controlled synthesis of complex peptides and supports scalable, reproducible workflows in medicinal chemistry and process development.
